## A. Prior to the lesson:

1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.

2. If their phone camera doesn't automatically detect and decode QR codes, ask students to

• Download a QR reader (e.g. I-Nigma | NeoReader | Kaywa) onto their mobile devices
• Bring these devices into the lesson.

4. Cut them out and place them around your class / school.

## B. The lesson:

1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.

2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.

3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!

## C. TIPS / OTHER IDEAS

4. A detailed case study in how to set up a successful QR Scavenger Hunt using this tool can be found here.

### Question

1. This is a LINE. It is a collection of points that continues forever in BOTH directions. Go find a PICTOGRAPH.
2. This is a PICTOGRAPH. It is a way to show data using symbols that represent a given amount. Always look for the key! Go find a DECIMAL.
3. This is a DECIMAL. It is a way we can show part of a whole. Decimals can have equivalent fractions. Go find a GROWING PATTERN.
4. This is a GROWING PATTERN. Growing patterns change in predictable ways. How is this one growing? Go find a MODEL OF ONE HALF.
5. This is a MODEL OF ONE HALF on a number line. Point A is located at the halfway point between 1 and 1. Go find a BAR GRAPH.
6. This is a BAR GRAPH. It is a way to show data using the bars to represent the total amount for each category. Go find an ARRAY.
7. This is an ARRAY. We use arrays to find products in multiplication. Arrays are made of straight rows and columns. Go find FIVE EIGHTHS.
8. This is FIVE EIGHTHS of a set. Sets are another way to show fractions. We use set models for things we shouldn’t break or cut. Go find a POINT.
9. This is a POINT. A point is an exact location in space. Go find a MODEL OF TWO WHOLES AND ONE FOURTH.
10. This is a MODEL OF TWO WHOLES AND ONE FOURTH. We could turn this model into an improper fraction or a mixed number. Go find PARALLEL LINES.
11. These are PARALLEL LINES. Parallel lines will never touch or cross (even if extended). They will remain the same distance apart forever. Go find PARTIAL PRODUCTS.
12. This is PARTIAL PRODUCTS. Partial products is a method to multiply larger numbers. The ability to break numbers down like this will really pay off in middle school! Go find THREE FIFTHS.
13. This is THREE FIFTHS of an area model. Area models are used for things we can cut or break. Fractions are made of a numerator and a denominator. Go find MULTIPLICATION ON A NUMBER LINE.
14. This is MULTIPLICATION ON A NUMBER LINE. We use number lines to model multiplication using hops of the same length. This model shows 2 hops of 3 will land on 6. Go find a RAY.
15. This is a RAY. A ray is a collection of points that continues forever in one direction. Go find a LINE GRAPH.
16. This is a LINE GRAPH. A line graph is used to show how things change over time. Sometimes they look like mountains. Always look at the bottom to see how often it is measured. Some things change slowly and some change quickly! Go find a REPEATING PATTERN.
17. This is a REPEATING PATTERN. Repeating patterns use the same pieces (core) again and again. We can name repeating patterns using letters like AB, ABC, ABBA etc. Go find a SET MODEL FOR MULTIPLICATION.
18. This is a SET MODEL FOR MULTIPLICATION. Sets can also be called groups. This model shows 3 groups of 4 for a total of 12. Go find LINE PLOT. (Look for X’s)
19. This is a LINE PLOT. Line plots are a fast way to represent a lot of data quickly on a number line. Each x stands for one data point. Go find PERPENDICULAR LINES.
20. These are PERPENDICULAR LINES. Perpendicular lines intersect (cross) in a special way that form right angles. You can draw a square in the corner to show others that there is a right angle. Now find a MIXED NUMBER.
21. This is a MIXED NUMBER. A mixed number is a way to write fractions that are greater than 1. It includes a whole number and a fraction. This one is read one and three tenths. Go find a LINE SEGMENT.
22. This is a LINE SEGMENT. Line segments are parts of a line. They have 2 endpoints. Go find a STEM AND LEAF PLOT.
23. This is a STEM AND LEAF PLOT. This a quick way to show numerical data. The stems represent the digit in the tens place and the leaves represent the digits in the ones place. This is a useful graph in 5th grade. Go find an IMPROPER FRACTION.
24. This is an IMPROPER FRACTION. Improper fractions show amounts greater than 1 whole. The numerator is greater than the denominator. This one is read thirteen fourths. You have completed the scavenger hunt. Go show this screen to Ms. Adams to get your prize! : )
